Bruno Senna has received a five-place grid penalty for changing his gearbox ahead of the Singapore Grand Prix.

The penalty drops Senna back from 17th to 22nd place on the grid after his qualifying session was ended prematurely on Saturday. Senna hit the wall exiting turn 21, breaking his right rear suspension in the process and preventing him from setting a time in Q2.

Since the end of qualifying it was discovered that the gearbox had been damaged in the incident and needed to be changed, dropping Senna back five places. Kamui Kobayashi, Vitaly Petrov, Heikki Kovalainen, Timo Glock and Charles Pic all move up one spot on the grid as a result.

It was the second time Senna had damaged his car this weekend having hit the wall exiting turn 19 in FP2 and missed the remainder of that session having caused a red flag. He now starts 20 places behind his team-mate Pastor Maldonado, who's impressive lap secured him second on the grid.
